From your chart we can all see that even IEOs are not perfect in terms of guaranteed returns. I also have a feeling that the buzz for IEO will die quicker than expected. Take a look at the latest IEO on binance for example. Perlin. A highly rated project that is struggling with a good return on investment due to its unimpressive price
No matter what it is, ICO, STO or IEO. None of them can give you a guarantee, in business everything is possible. And the IEO has started its decline these couple of months, almost 80% of our total exchanges are doing shit with their IEO. Just look at IDAX for example, they ask you 10BTC for the IEO listing but when it starts, some project only could gather at most 2BTC from the IEO. This explains the IEO buzz is already on the decline.
